Phase 1: Demonstrate your ability to control pain by piercing a fish hook through your skin.

Phase 2: Display your uncanny ability to control your blood flow by moving the hook around without a single drop of blood.

Phase 3: Rip the fish hook from you flesh and appear to heal instantaneously in a supernatural manner.

...All of this takes place while the spectator holds on to one end of the hook.

Hook is Andrew Mayne's devious update to the classic needle through arm effect. Shove an unprepared fish hook through your arm while a spectator holds on to one end of it at all time. For a disturbing finale, you rip the fish hook straight out of your arm completely unharmed.
